My baby Peanut home was cut down and he took a b8g fall. I believe he already had a little damage to his back left leg. I put in in a bigger cage, which I didn't realize he was still too small, and one night he woke me up crying out. I just thought he got lost in his new cage and got scared. The next day I realized his left back leg was hurt and swollen near the hip. He still moves it, so I don't think it's broke, but how would I know if it's dislocated?
